移动视图viewport 禁止缩放

<meta name="viewport" content="width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=0">

先来假设本机A，远程服务器是B。

需要在本机A生成ssh密钥：ssh-keygen -t rsa

然后复制~/.ssh/id_rsa.pub的东西【密钥】，windows是在C:\Users\用户\.ssh\id_rsa.pub

然后登录远程服务器，在~/.ssh目录下建立authorized_keys文件【vim authorized_keys】

将上面的~/.ssh/id_rsa.pub里面的东西复制进去。

Laravel 在谋篇文章中获取上下一篇。

$prev_article = Article::where('id', '<', $id)->orderBy('id', 'desc')->first(['title', 'id']);
$next_article = Article::where('id', '>', $id)->orderBy('id', 'asc')->first(['title', 'id']);

tip: title为文章标题字段，id为id字段（废话不是）。网上的代码是没有['title', 'id']，没有加的话获取整篇文章的所有字段，总感觉有丢丢耗性能。

swal 选择是否删除 模板

swal({
    title: "确定删除吗？",
    text: "删除不可逆！",
    icon: "warning",
    buttons: true,
    dangerMode: true,
})
    .then((willDelete) => {
        if (willDelete) {
            axios.delete('/admin/SiteConfig/' + id)
                .then(res => {
                    if (res.data.status === 1) {
                        swal({
                            text: res.data.msg,
                            icon: 'success',
                            buttons: false,

                        window.location.reload();

JavaScript实现按照指定长度为数字前面补零输出的方法

方法一

function PrefixInteger(num, length) {
     return (Array(length).join('0') + num).slice(-length);
}

方法二

function PrefixInteger(num, length) {
     return ( "0000000000000000" + num ).substr( -length );
}

Python抓取某些资料并通过PHP提供的接口写入到数据库的模板。

安装最新版

composer require barryvdh/laravel-debugbar --dev

发布

php artisan vendor:publish --provider="Barryvdh\Debugbar\ServiceProvider"

摘自知乎：https://zhuanlan.zhihu.com/p/72923073

函数的防抖

function debounce(func, delay) {
    let timeout;
    return function () {
        clearTimeout(timeout); // 如果持续触发，那么就清除定时器，定时器的回调就不会执行。
        timeout = setTimeout(() => {
            func.apply(this, arguments)
        }, delay)
    }
}

函数的节流

function throttle(func, delay) {
    let run = true;
    return function () {
        if (!run) {
            return  // 如果开关关闭了，那就直接不执行下边的代码
        }
        run = false; // 持续触发的话，run一直是false，就会停在上边的判断那里
        setTimeout(() => {
            func.apply(this, arguments);
            run = true // 定时器到时间之后，会把开关打开，我们的函数就会被执行
        }, delay)
    }
}

Phpstorm 还需要安装laravel-plugin插件。

laravel-ide-helper

使用composer安装插件

composer require --dev barryvdh/laravel-ide-helper

生成代码跟踪支持

php artisan ide-helper:generate

非原生实现。

$images = Bing::inRandomOrder()->take(10)->get();

某个脚本，加油。
